Clearblue® Digital Pregnancy Test with Smart Countdown is more than 99% accurate in laboratory tests, when used from the day you expect your period.

For your result to be 'Pregnant' (positive) there must be a blue line in the control window and a '+' symbol in the result window within 10 minutes of testing. It does not matter if one of the lines that make up the '+' symbol is lighter or darker than the other; the result is 'Pregnant'.

The pregnancy hormone increases rapidly in early pregnancy and Clearblue® Digital Pregnancy Test can be used as early as 5 days before the missed period (4 days before the expected period).

Clearblue Early Detection Pregnancy Test provides early detection of the pregnancy hormone. 71% of pregnancies can be detected 6 days before the missed period (5 days before the expected period) and 94% of pregnancies can be detected 5 days before the missed period (4 days before the expected period).

Know this: All Clearblue® pregnancy tests are over 99% accurate from the day you expect your period. False positives very rarely occur, and are often due to medical conditions or certain medications. False negatives, while more common, typically occur due to testing too early or drinking too much liquid before testing.

If you see a positive result beyond this time frame, you may be left second-guessing the results. However, always remember that a pregnancy test result is only accurate within 10 minutes. After the that, it's best to throw the test away to avoid confusion.

A positive pregnancy test result will typically either show up as a plus sign, two double lines, or one line in a results circle or window, though there are other kinds of test results, including the digital ones that show the word "yes" or "pregnant" when they're positive.

For single window tests a positive result would show both the test line and another line to indicate that you are pregnant. For the two-window tests, in the control window, a test line would appear and in the second window, a plus sign (+) will appear (even if it is faint) to indicate that you are pregnant.
